The 1974 model Eldorado is a three-ton behemoth with a 500-cubic-inch engine that is long on style but short on gas mileage.During its five-year development process no one could possibly have anticipated that gas prices would go through the roof in 1973,making it far more expensive to operate and subsequently less attractive to a gas-price-conscious public.Design engineers scrambled to change the car in the last few months leading up to its debut,adding a slimmed down version with a smaller engine.All of the design overtime meant that the project budget took a big hit though,thanks to:
A)the initial low estimate.
B)the unexpected technical difficulties.
C)this external factor.
D)the lack of definition.
